Scope of Estoppel Considered for Review

IPR estoppel is defined by 35 U.S.C. 315(e). The statute recites in relevant part that any claim subject to a failed IPR may not be argued by that petitioner in an infringement action as “invalid on any ground that the petitioner raised or reasonably could have raised during that inter partes review.” 315(e)(2)

While there has been much debate in the lower courts as to the scope of “reasonably could have raised,” and even “ground,” the debate currently before the SCOTUS in Apple et al., v. California Institute of Technology turns on the meaning of “during.” That is, whether “reasonably could have raised” is assessed at the time the petition is drafted, or, during the actual proceeding. If estoppel is determined at the outset of petition drafting that scope is far broader than what could be added to an ongoing IPR proceeding (i.e., next to nothing).

Should this question ultimately taken up, the outcome could have significant consequences.…

Would a “Mini-Markman” Have Helped Patent Owners?

A long time ago, in a galaxy, far, far away….the Patent Trial & Appeal Board (PTAB) considered implementing a Markman style claim construction procedure it labeled a “Mini-Markman.” The idea, along with others was the result of a 2015-16 listening tour conducted by the agency under former USPTO Director Michelle Lee. The listening tour stopped at several locations across the U.S. to collect public feedback on AIA trial proceedings. The tour culminated in a draft rule package that contained a number of interesting ideas. Needless to say, that rule package was abandoned and never saw the light of day (for reasons unknown)

As we move into the new year and look forward to coming PTAB rule packages on discretionary denials and rehearing practices, I revisit this old idea in view of the never ending dialog on reforming the PTAB.…

Re-work Frustrates Patent Owners & The System

I have written about Patent Owner estoppel for years. That is, estoppel stemming from claims cancelled in PTAB trial proceedings. This estoppel is based on the idea that, if you have an amendment to bring to a given claim set, you should bring that amendment during the trial — not thereafter, such as in a patent reissue, reexamination or continuation application.

Rule 42.73 (d)(3)(i) explains that a Patent Applicant or a Patent Owner is precluded from taking action inconsistent with a claim cancellation, including, obtaining in any patent a claim that is not patentably distinct from a finally refused or cancelled claim. But, it is fairly common for unsuccessful Patent Owners to go right back after a PTAB loss and pursue substantively identical claims through patent reissue or reexamination. Why?

Patent Owners are not gluttons for punishment, they are just following the directions of the agency.…

Ending Opensky IPR Participation Underwhelming

Back in March, I explained that the Opensky mess needed to be immediately checked by the USPTO. The legitimacy of the PTAB is at stake when when profiteers are actively conspiring to abuse the IPR process by offering to deliberately file papers for an improper purposes. The situation called for swift and decisive correction…..but this is the federal government. So, we waited for a new Director to be appointed, and then, largely unnecessary amicus briefing for such a unique fact pattern.

Six months later (IPR is effectively done except for the Final Written Decision), we finally have a determination out of the Director. But, the outcome is far from satisfying for anyone that is hoping for the PTAB to start policing bad actors akin to an Article III Court.…

Long Battle Ahead for Patentable Subject Matter Clarity

Remember the good ole days when every bar meeting had that Alice panel that said the same thing over and over? (i.e., “your guess is as good as mine”) And by good ole days, I mean the days when you skipped that panel and caught up on your emails back in your room. 🙂

Well, here we go again.

With American Axle failing to tempt the SCOTUS, the message has become clear….”Congress, this is your mess to fix.” So, we now embark on yet another adventure on sorting out the patent world’s biggest hairball – and that’s saying something!…
